Be it known that I, CHRISTIAN 'Sanus/inne," a citizen of theUnited States oi' America,`

and a 'resident of Detroit,county ofi/Vayne,

Y 5 and State of Michigan, have invented cer# -tain new and useful Improvement-sin Spindescription, such asl will i enable ot-hers skilled in the art to which the inventionv'relates to make and use*y the saine, reference` beifngimadetherein to the accompanying y drawings, which lform aI part of this specifi-V cation.A

My invention'relates to' tools or appliances used in the repair O-f-automobiles and similar self-propelledvehicles; andthe prin-,-

cipal object'thereois .to provide anim` proved device for "use in removing the bolts or spindles whereby thel steering knuckles which carry the stub" axles for the 1 front wheels are pivotally connected with thev front/axle between the-arm's-Yof yokes, one' l at each end of the axle;V A further object of'my inventionfiislt provide va device for the purposestated and lby the use of which spindle bolts or steering knuckle pivots may be removed from the yokes and knuckles without injuring them,` as by bending or bruising them, breaking the threads at the end thereof, or otherwise,

- as commonly results whenthe bolts are re-l moved by the use of. a hammer' and punch; andy which devlcewill be simple in construc- 3,-, tion and easy to apply and use, and generi' ally effective for the use for which it isdesigned. l i

With the above andother objects in view,

i my invention f consistsl in the improved 4o spindle bolt removing'device illustrated in its preferred forni inthe drawing accom-r panying and forming apart of this specification, and: hereinafter described in detail and finally claimed; and in suchvariations 4,-, and modifications thereof, within thescope of the concluding claims, as will be obvio-us to those skilled inthe-art vention'relates. v o
